On SitePoint's Web blog today there's a post from Rakhitha Nimesh showing you how to create presentations with WImpress, the second part of their series on using the impress.js Javascript library (part one is here).

In the first part, we learned how to integrate impress.js into WordPress, for creating dynamic presentations with CSS transitions and transformations. impress.js is becoming one of the most popular JavaScript libraries in Github. [...] In this tutorial, we are going to look at the possibilities of enhancing the default features of impress.js while building an interactive presentation with WImpress.

They walk you through the creation of a simple presentation, complete with all the code you'll need. They show how to create the "options" page and add it to the WordPress site structure. The process allows you to specify text and a background image reusing some of the built-in WordPress functionality. They've also included some examples of the results for three different levels of a presentation - a simple single slide, adding "second level" steps and building a cube.
